There are many
ways to divide fractions: |
|
In this
lesson, you will explore the fifth method: Multiplying by a
Reciprocal. This is the most common method used
to divide fractions. It is used when measurement and
partitioning are not easily done, and the denominators are not like. |
|
So let's
quickly review an important term: |
|
reciprocal |
sometimes
called the multiplicative inverse-"switch" the fraction around- the
numerator becomes the denominator and the denominator becomes the
numerator! |
Now the rule is simple:
to divide fractions, multiply by the reciprocal of the second
number. (4/3 is the reciprocal of 3/4, and 7/6 is the
reciprocal of 6/7.)
